In accordance with the present invention, there is provided an air conditioner, comprising refrigerating system, ventilating system, electric controlling system, indoor unit shell and outdoor unit shell, characterized in that, it further comprises at least one connection rods, the indoor unit shell and the outdoor unit shell is connected by said connection rods; in the refrigerating system, by way of totally-enclosed welding, the compressor is connected with its intake pipe and with its discharge pipe, the condenser is connected with the discharge pipe of the compressor and with the capillary tube, the evaporator is connected with its intake pipe, and the intake pipe of the evaporator is connected with the capillary tube.
The air conditioner in accordance with the present invention further comprises a damper corrugated soft pipe. Said intake pipe of the compressor is divided into at least two segments, and the two segments are connected by said damper corrugated soft pipe which is made of materials that can withstand corrosion, high temperature and high pressure. Said intake pipe of the compressor is connected with said damper corrugated soft pipe by way of totally enclosed welding.
The air conditioner in accordance with present invention further comprises noise deadener, which is installed between the indoor unit and the outdoor unit.
Wherein said connection rod is connected in removable mode, and said damper corrugated soft pipe is made of metal.
By implementing the air conditioner according to the present invention, compared with conventional split-type air conditioner, the consumption of raw material can by reduced by 15%, the weight can be reduced by 10%, and the production cost can be reduced by 15-20%. It has advantages of compact in volume, low production and transportation cost, easy and secure for installation. Since the outdoor unit is not fixed on the outside wall, there will be no risk for outdoor unit to fall down and hurt passengers. In addition, by way of totally-enclosed welding, there will be no refrigerant leakage. And thanks to the connection rod, damper corrugated soft pipe, and noise deadener the noise and oscillation caused by the compressor and condenser is blocked outdoors, and the noise indoors is greatly lowered. In addition, outdoors fresh air can be supplied indoors, moving and relocation is as easy as window air conditioner.
